SPECIFICATION forming part of Letters Patent'No. 567,022, datedSeptember 1, 1896.

Application filed February 1l., 1896. Serial No. 578,906. (No model.)

To all whom, t may concern:

Be it known thatyve,.IACOB F.DIEHL,JACOB F. DIEHL, J r., and DANIELDIEHL, of Pittsburg, in the county of Allegheny and yState ofPennsylvania, have invented a new and useful Improvement inElectric-Light Hangers, of which the following is a full, clear, andexact description.

Figure 1 is a side elevation of our improved lamp-support, showing thelamp in different positions; and Fig. 2 is an enlarged detail view withthe trolley broken away.

Our invention relates to the supporting of electric lamps by means of amast having a projecting arm, and is designed to provide a simple andeffective means whereby the lamp may be lowered into convenient positionfor changing the carbons or otherwise adjusting the lamp.

In the drawings, 2 represents a mast having secured thereto a projectingarm 3, this arm extending rearwardly beyond the mast, to which it issecured by a side clip 4, and havinga depending pivoted brace 5, bywhich the angle of inclination of the arm may be altered as desired. Asecond brace G leads from the outer end of the arm upwardly to the mast,this arm being inclined downwardly from the mast toward its outer end.Upon the arm, which is preferably in the form of a hollow rod, moves thetrolley 7, having the supporting-wheels 8, which travel upon the arm,this trolley being drawn rearwardly up the inclined arm toward the mastby a oord 9. This cord is secured to an eye 10 in the forward portion ofthe trolley, thence passes over a small pulley 11, pivoted within a loopor yoke 12, to which the lamp is suspended, thence over a pulley 13,supported in the trolley, and over a stationary pulley 14 upon the mast,and then downwardly to the securingcleat 15. lVithin the trolley andprotruding forwardly therefrom are two loosely-pivoted hook-jaws 16 and17, the lower jaw 17 normally resting against a stop 18,while the upperjaw overlaps and rests upon the end of the lower jaw.

The operation is as follows: The lamp being in its position at the outerend of the arm, when it is desired to lower the same the operator,detachin g the cord from the securinging from our invention, since cleatand drawing downwardly upon this cord, pulls the trolley rearwardly upthe inclined arm until it reaches a stop 19, which prevents furthermovement of the trolley. A further pull upon the cord lifts the yoke 12against the upper jaw 16, which, swinging upwardly, allows the yoke topass into the position shown by dotted lines in Fig. 2. The operatorthen paying out the cord, the lamp is lowered into the position shown bydotted lines in Fig. 1. Then it is desired to return the lamp to itsoriginal position, the operator, drawing downwardly upon the rope,raises the lamp upwardly until the yoke 12 strikes the lower swingingjaw 17, as shown in full lines in Fig. 2. A further pull swings bothjaws upwardly until the parts reach the position shown in dotted lines,when the lower jaw swings downwardly, and the cord being let outslightly the yoke enters the space between the jaws, and the upper jawdrops down into a normal position by gravity. The cord then being paidout, the lamp runs down the incline by gravity until it reaches itsoutermost position.

The advantages of our invention will be apparent to those conversantwith this art, sincepa single rope or cord enables the operator todetach the lamp from the trolley to lower it to a point near theground,-to raise it and support it upon the trolley, and to change thepositions of the trolley upon the arm. The trolley is inexpensive, andthe whole device is very simple and not liable to get out of order or tobecome impaired in its action by exposure.

Many variations may be made in the form and arrangement of the partswithout depart- "We Claim- 1. rlhe combination with a mast having alaterally-projecting arm, of a trolley movable upon said arln, a cordarranged to draw the trolley along the arm, a stop upon the arm arrangedto engage the trolley, and means operated by the cord for det-aching thelamp from the trolley after the trolley is drawn against the stop;substantially as described.

2. The combination with a mast having a laterally-projecting armprovided with a trolley-stop, of a trolley movable along the arm, a

IOO

hanger for the lamp removably supported within the trolley, and a cordsecured at its outer end to the trolley and passing through thelamp-hanger, said cord being arranged to draw the trolley along the arxnand to detach the lamp from the trolley; substantially as described.

The combination with a mast having a laterally-projecting arm providedwith a trolley-stop of a trolley movable along the arm, a swinging hookpivoted within the trolley, a lamp-hanger supported upon the hook, and acord secured at its outer end to the trolley and passing thence under apulley in the lamphanger, said cord being arranged to draw the trolleyalong the arm and to detach the hanger from its supporting-hook;substantially as described.
